I am attempting to make a towing hydrophone for listening to whales. I am following the instructions posted by NOAA here: https://swfsc.noaa.gov/uploadedFile... et al 2008 HydrophoneConstruction_TM-417.pdf
I have completed my board, but it doesn’t produce any sound. Looking for some help on diagnosing where I may have gone wrong....
Are my capacitors backwards? Wrong preamp chip? Not really sure.
Any help would be greatly appreciated.
